  • 製品概要

    The MAX8760 evaluation kit (EV kit) demonstrates the high-power, dynamically adjustable multiphase notebook CPU application circuit. This DC-DC converter steps down high-voltage batteries and/or AC adapters, generating a precision, low-voltage CPU core VCC rail. The MAX8760 EV kit meets the mobile AMD K8 and K8 Rev F VID code set and CPU transient voltage specifications. The MAX8760 EV kit consists of the MAX8760 dual-phase Quick-PWM™ step-down controller and the MAX6509 temperature sensor.

    The MAX8760 EV kit includes active voltage positioning with adjustable gain, reducing power dissipation and bulk output capacitance requirements. Precision slew-rate control provides "just-in-time" arrival at the new DAC setting, minimizing surge currents to and from the battery.

    This fully assembled and tested PC board provides a 6-bit digitally adjustable output voltage from a 7V to 24V battery input range. The EV kit operates at 300kHz switching frequency and has superior line- and load-transient response.
